JailbreakMe PS4 4.0x: PS4 4.0x WebKit RCE Exploit by Qwertyoruiopz!

Following the PS4 Playground for Firmware 3.55 and PS4 3.55 File Browser, today PlayStation 4 developer qwertyoruiopz made available a PS4 4.0x WebKit RCE Exploit dubbed JailbreakMe PS4 4.0x with details via Twitter below!

According to the developer's Tweets below, the bug used is a stack uninit read yielding UaF and the actual exploit does nothing but give you read/write/infoleak arbitrary JS object primitives.

He also confirmed the exploit won't work on PS4 4.50 as Sony updated WebKit past a vulnerable version unfortunately, but it's still an entry point for those on PlayStation 4 OFW 3.55 through 4.07.

That said, if you give it a try on a PlayStation 4 under 4.50 and receive a ffff000000000539 error prompt it's expected output for the exploit's success.

[hector09]

should i upgrade my Firmware to 4.07? or should i remain on 3.70 before doing this exploit. I have a PS4 Pro btw

 

[PSXHAX]

It should work on PS4 OFW below 4.50, so if I were you I'd stay on 3.70 and give it a try

 

[DoxyMarket]

Let's the fun start.... Since most ps4 are in 3.55 well at least me lol.. the scene will move fast and quick..

im sure it would work on 3.70, but since theres new games i can play with update 4.07 i wanted to get to that update and still do the exploit. So thats why i wanted to know if it be better to update to 4.07 and then try the exploit.

Also if i do the exploit on the 3.70 and then decide to update to 4.07, i will need to do the exploit once more right?

Im on 4.50 beta for and since to finally version of 4.50 came out im pretty sure i cant go back to 4.07 through system update function. Do you think it will work if I update through safe mode to 4.07
